Abstract

The Nd 3 + Yb 3 + energy transfer spectral characteristics in ( Nd , Yb ) : Y 2 O 3 ceramics and the relevant spectral and emission decay data on single-doped (especially temperature effects) and codoped samples are presented. The transfer efficiencies depend strongly on Yb 3 + content, attaining 98 % for Nd 1 at. % Yb 5 at. % at 300 K . The resonant Nd 3 + Yb 3 + energy transfer ( F 3 2 4 ( Nd ) , F 7 2 2 ( Yb ) ) ( I 9 2 4 ( Nd ) , F 5 2 2 ( Yb ) ) , involving Nd 3 + in C 2 sites and Yb 3 + in C 2 and C 3 i sites, is dominated by a dipole–dipole interaction with a microparameter C DA , Nd Yb 1 × 10 38 cm 6 s 1 at 300 K . The possibility of using this system for Nd-sensitized Yb 3 + laser emission from room-to-cryogenic temperatures is discussed.
